Anti-RFLNB antibodies are used in the immunodetection of the protein refilin B. In humans, the canonical protein has a reported length of 214 amino acid residues and a mass of 22.9 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed in the tonsil, spleen, and bone marrow. A member of the Refilin protein family, RFLNB is reported to be involved in regulation of the perinuclear actin network and nuclear shape through interaction with filamins. Synonyms for this target antigen include filamin-interacting protein FAM101B, protein FAM101B, regulator of filamin protein B, and family with sequence similarity 101, member B. RFLNB gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Western Blot is the most common application for the RFLNB antibodies listed below. Immunocytochemistry and Immunofluorescence are also common applications.
